mercial applications:
Schools, Offi ce buildings, Churches, Retail stores,
Nursing homes, Hotels/motels, Common or offi ce areas
In such applications , the furnace must be installed with the
following stipulations:
• It must be installed per the installation instructions
provided and per local and national codes.

• It must not be used as a “make-up” air unit.
• All other warranty exclusions and restrictions apply.
This furnace may be used as a const ruct ion sit e heater ONLY
if all of the following condit ions are met :
• The vent system is permanently installed per these
installation instructions.
• A room thermostat is used to control the furnace. Fixed
jumpers that provide continuous heating CANNOT be
used and can cause long term equipment damage.
Bi-metal thermostats, or any thermostat affected by
vibration must not be used during construction.
• Return air ducts are provided and sealed to the
furnace.
• A return air temperature range between 60ºF (16ºC)
and 80ºF (27ºC) is maintained.
• Air fi lters are installed in the system and replaced
daily during construction and upon completion of
construction.
• The input rate and temperature rise are set per the
furnace rating plate.
• 100% outside air must be used for combustion during
construction. Temporary ducting may be used to
supply outside air to the furnace for combustion – do
not connect this duct directly to the furnace. Size this
duct according to NFPA 54/ANSI Z223.1 section for
3. With concealed damage, carrier must be notifi ed as

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
NOTE: Discharge body’s static electricity before touching
unit. An electrostatic discharge can adversely affect electrical
components.
Use the following precautions during furnace installation and
servicing to protect the integrated control module from dam-
age. By putting the furnace, the control, and the person at
the same electrostatic potential, these steps will help avoid
exposing the integrated control module to electrostatic dis-
charge. This procedure is applicable to both installed and
non-installed (ungrounded) furnaces.
1. Disconnect all power to the furnace. Do not touch the
integrated control module or any wire connected to the
control prior to discharging your body’s electrostatic
charge to ground.
2. Firmly touch a clean, unpainted, metal surface of the
furnaces near the control. Any tools held in a person’s
hand during grounding will be discharged.
3. Service integrated control module or connecting
wiring following the discharge process in step 2. Use
caution not to recharge your body with static electricity;
(i.e., do not move or shuffl e your feet, do not touch
ungrounded objects, etc.). If you come in contact with
an ungrounded object, repeat step 2 before touching
control or wires.
4. Discharge your body to ground before removing a new
control from its container. Follow steps 1 through 3 if
installing the control on a furnace. Return any old or
new controls to their containers before touching any
ungrounded object.
TO THE INSTALLER

to familiarize yourself with specifi c items which must be ad-
hered to, including but not limited to: unit maximum external
static pressure, gas pressures, BTU input rating, proper elec-
trical connections, circulating air temperature rise, minimum or
